I have checked the documentation for downloading on windows live account and the issue with the windows with fall creator update.
I have previously tried to download on a windows where there is just a Microsoft live account, this failed and stopped the user from entering into their account. (bare in mind this is an admin account)
next I added a local admin account and added DUO and then that stopped the user from entering any password for any of the accounts. we had to go into safe mode and wipe data.
honestly im lost and I need this user to have Duo installed properly, is there any way I can get this to work ?
